I know when I was still attending there was an inactive witness that owned a local caf and she started putting full on xmas displays in the window of the caf one year they did investigate but decided she had been inactive for so long they wouldn't pursue it.
She did come from a large influential witness family mind you and local witnesses patronized the business that could well have inflenced their decision because she was definitely known as a witness by the community at large.
These things are often arbitrary and capricious in nature as to how they are handled locally.
